Okay, so you know how when you play make-believe games, you might pretend to be a firefighter, a doctor, or a superhero? Well, some people pretend to be a soldier or a member of the military even though they're not really one.
This isn't okay because being in the military is a very important job where people have to work hard, be brave, and protect our country. When someone pretends to be a military person, it can be disrespectful to the actual military members who work really hard to keep us safe.
Sometimes these pretend military people even wear fake uniforms or medals that they didn't earn. That's a very bad thing to do because it takes away the value of the real medals that people earned by doing important things in the military.
So it's important to remember that pretending to be in the military when you're not is not cool, and we should always respect the real military members who work hard to keep us safe.
